SHUTTLE FOR BOBBINS.

Refiled for abandoned application serial No. 532,948, filed. January 31, 1922, This application filed To all whom it may concern:

Be it known that 1, JOHN B. BENTLEY, a citizen of the United States, residing at the city of Jamestown, in thecounty of Chautauqua and State of New York, haveinvented certain new and useful Improvements in Shuttles for Bobbins, of whi'ch the following, taken in connection with the a ccompanying drawings, is a specification.

This application is a substitute for my earlier application Serial n -532,948 filed January 31st, 1922 andlater abandoned.

shuttle shell. 7 Fig. 4 is a side elevation of the same show- The invention herein relates to shuttles to be used in looms for weaving, and the improvement is a simplification of the construction shown in my Letters Patent 1,392,042, of September 27, 1921, consisting in providing a split spindle in theshuttle shell or weft case with the clip or bracket thereinhaving an openrended slot enlarging inwardly so that the split spindle canbe sprung intothe same to hold said spindle firmly in position, the end of said spindle being hooked or turned sidewiseso as to prevent said spindle moving endwise when inserted in said bracket, and at the same time permitting said spindle to bemoreea'silyiin serted and much more durable thanin my previous construction; also, to providea tension spring for the hooked end of said spindle which is held inposition by one of the attaching screw bolts for said bracket, the holding tension on the spindle beingialways the same; and the invention consists'in the novel features and combinationsYhereinafter set forth and claimed. i 1 i In the drawings, Figure 1 is a top pla view of the shuttle with the spindle in position therein. Y 1 a i i Fig. 2 is vertical lengthwise sectional view of the same with the bobbin on the spindle, and showing the construction and arrangement of the improved parts infposition in the shuttle shell. I

Fig. 3 is a top plan view of thepreferred form of the split spindle removed from the ing the upwardly hooked end.

Fig. 5 is a lengthwise sectional View of the attaching end of the spindle with said spindle in the raised position as when being inserted or removed.

Fig. 6 is a crosswise sectional view of the spindle showing an elevation of the bifurcated end of the holding elip, said spindle being shown within the inward enlargement of the open ended slot in'said clip into which it has been sprung."

Fig. '7 a perspective view of the holding clip or bracket; and i Fig. 8 is a perspective View of the tension spring which is attached within the shuttle shell by one of the attaching screw bolts for said holding clip or bracket.

Like characters or references refer to corresponding parts in the several views.

"The numeral 10 designates the shell or Weft case which is pointed and tipped at each end in the usual manner and has the length- ,wise slot or bobbin chamber 11 therein forv the split spindle 12 and the spool or bobbin one end to receive therein the holding bracket or clip 14, which holding bracket 14is provided with the raisedor inverted U-shaped end 15 which fits over the crosswise holding rib 16 in the wooden shell 10. The crosswise holding rib 16 provides the crosswise slot 17 between said rib 1,6 and the end wall of the groove 13. The end leg 18 of the clip or bracket 14 is preferably round cornered so as to be easily inserted in the slot 17 over the rib 16, thereby firmly holding said clip 14 in position within the groove 13. I

f-The holding bracket or clip 14 is preferably attached in said groove 13 by means of two screw bolts 19 and 20 which firmly fasten the holding clip or bracket 14 in position. The bifurcated end 21 of the clip or H slot 11 has the extension groove 13 at bracket 14 extends upwardly and has the raised portion 15, and thespindle 12 has the upwardly hooked end or" butt 25 which hooks within the hole 24 engaging against the inner wall of said raised portion to prevent endwise movement of said spindle.- A spring 26 is provided in the bottom of the groove 13 having an upturned end 27 and a hole 28 for attachment by means of the screw bolt 19, which extends down through the hole 28, said spring 26 being of sufficient rib 16 so that when the hooked butt 25 of spindle.

the spindle 12 is inserted through the hole 24:, it will spring said upturned end 27 toward the rib 16, thereby holding said butt 25 and the spindle firmly in the hooked position within the hole 241, preventing all endwise movement of said split spindle 12.

An enlargement 30 is provided on the outwardly curved sides of each of the split spindle portions for the butt of the bobbin 31 to rest upon and hold the bobbin in the alignment with the tip portion 32 of said The bobbin 31 is placed upon the spindle 12 by raising the split spindle 12 out of the slot 22 of the holding jaws 24:, the hooked butt 25 permitting the upwardly turning movement as shown in Fig. 5, thereby easily removing the spindle 12 from the shuttle shell and permitting the insertion of the butt 25 and spindle through the hole in the bobbin or spool 31, after which said spindle with the bobbin thereon may be quickly inserted within the holding bracket or clip 14, holding said spindle atsu ch tension that the parts cannot wear or get out of position.

The spindle 12 is preferably made of spring steel semi-cylindrical parts, which are shaped to contact one another at their tip and butt portions and bow outwardly a spaced distance from each other throughout their central portion, said central portions being substantially parallel to one another.

The tension spring 26 is held firmly in position by theattaching bolt 19, thereby rendering the assembling of the parts easy of attainment, yet holding the butt 25 and spindle 12 always in the correct position under tension.

The hooked butt 25 of the spindle 12 is formed by the two hooked ends of' the semi-c lindrical parts of said split spindle, whic semi-cylindrical parts are given a slight rocking attachment to one another by the loose rivet 33 extending through the ends which arrangement permits a free springing action of the split spindle parts in the hooked butt 25, the same as in my former Letters Patent.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent ist' 1. In a shuttle a holding clip having an inverted U shaped outer end and upturned inner end in which inner end is formed an open ended inwardly enlarging slot, in combination with a resilient split spindle adapted to spring into holding engagement in said open ended slot, and a hooked end portion on said spindle engaging the U shaped end of said clip and thereby securing said spindle in position.

2. In a shuttle a holding clip having an inverted U-shaped outer end in which is provided a hole and an upturned inner end in which is provided a open ended slot, a screw for mounting said clip in said shuttle, a split spindle having a hooked butt adapted to be inserted into said open ended slot with the butt in said hole to prevent endwise movement and a tension spring bearing against said butt fixed in the shuttle by the screw for said holding clip.

3. In a shuttle, a bifurcated member, a spindle having a pair of oppositely disposed spring members attached to one another in their end portions and spaced from one another throughout their central )ortion, said members upwardly hooked at tie butt end of the same, a perforated member formed to receive said hooked ends of said members, said bifurcated member being formed to engage said members in front of said hooked ends thereof so as to compress same and thereby hold the same, and a spring member to hold said hooked end within said perforated member.

*4. In a shuttle, a shuttle shell having a lengthwise pocket to receive spindle and bobbin, a crosswise rib in one end of said pocket a holding clip having an inverted U-shaped outer end one leg of which is receivable between the said rib and the end of said pocket, the inner end of said holding clip being upturned and having an open ended inwardly enlarging slot therein, a tension spring in the U-shaped portion of said holding clip bearing against said crosswise rib, said holding clip having an opening therethrough, in front of the rib-engaging portion of said tension spring, a split spindle having a hooked butt insertable through said opening and tensionally held by said spring to prevent endwise movement of said spindle which spindle is receivable in the inwardly enlarged portion of said slot and thereby held removably in perfect alinement in said pocket.

In testimony whereof I have aflixed my signature.

JOHN B. BENTLEY.
